Joseph Millar produced the performance of the meeting on the final day of the Jennian Homes New Zealand Track & Field Championships in Hamilton with a stunning 200m victory in 20.37s.

The time, with a negligible 0.1 tail wind, broke two long standing New Zealand records, the national record of 20.42, set by Chris Donaldson in 1997 and the resident record of 20.61, set by Matthew Coad a year earlier.

It also went under the 20.44 selection standard for the London 2017 World Championships and nomination standard for the 2018 Commonwealth Games on the Gold Coast.

Millars 200m performance coupled with his win in the 100m in a quick 10.18 give the Tauranga athlete his fourth national sprint double victory, to go with his wins in 2012, 2013 and 2014. He also led his Waikato Bay of Plenty team to victory in the 4x100m relay.

As expected, Rio bronze medallists Tom Walsh and Eliza McCartney won their respective events, Walsh belting out an impressive 21.51 in the second round to secure his eighth national title and set a new championship best performance, surpassing his 21.11 in 2016.

McCartney, by her own admission, had an off day, but still cleared 4.55 to easily win the womens pole vault title for the third consecutive year in her relatively short career.

The race of the day was the womens 1500m which boasted a deep field and lived up to those expectations. The two most recent champions Angie Petty and Nikki Hamblin, both Rio Olympians were joined by Camille Buscomb, 800m runner up Katherine Camp, 5000m champion Laura Nagel and Esther Keown.

The six ran as a tight bunch with the lead changing several times before Buscomb took charge for the last 600m, with Petty hot on her tail and Hamblin and Camp not far back. Petty squeezed past Buscomb on the last 200m and went on to claim her second win in the championships, following her 800m win the day before.

The mens 1500 title went to Hawkes Bays Eric Speakman, two places better than his 800m bronze.

Zoe Hobbs added the womens 200m title to her 100m victory on Friday, recording a personal best of 23.85.

400m hurdles championship wins went to Waikato Bay of Plentys Cameron French in 51.58 to go with his 100m bronze and Anna Percy from Canterbury who defended her 2016 title in 60.23.

Steeplechase winners were Rosa Flanagan (Canterbury), back from a long injury break and Jack Beaumont from Southland.

Graeme Jones from Hawkes Bay Gisborne took out the mens 20km race walk to repeat his victories in 2013 and 2015. The womens race was won by American visitor Erin Talcott but the title went to Rozie Robinson, her fourth title in the event.

The final events of the championships, the 4x400m relays were won by Manawatu/Wanganui (men) and Canterbury (women) with host Centre Waikato Bay of Plenty runners up in both races.
